How many lakes are there in Russia? It is still impossible to give an exact answer to this question today. Many, many – more than 2 million. Among them there are famous, great lakes - “the blue eyes of the planet.”

The deepest, and perhaps the most famous lake on the planet - Baikal. It could hold a hundred Seas of Azov, but the water of Baikal is fresh, and this is the special value of this huge natural reservoir. The maximum depth of the lake is 1637 meters, and under the water column there are huge bottom sediments, or so-called mountain ranges, the height of which is about 7000 meters. On fine days the water is so clear that you can see the bottom at a depth of 40 meters. Baikal water - living water, since, thanks to phytoplankton, the maximum amount of oxygen is dissolved in it. Another of its properties is low temperature, which even in summer is not higher than +10 degrees. There is a legend that at the bottom of Baikal there is a huge channel that connects the lake with the Arctic Ocean. Baikal is about 30 million years old, and there are no signs of aging. On the contrary, over the course of a year, the lake’s waters “conquer” about 2 centimeters from the land.

Caspian Sea

The largest on the planet closed lake– The Caspian Sea, however, did not get its name because impressive size(371,000 km?). The reason is that the bottom of the lake is oceanic type crust, and the salinity of its waters is high. The Volga, which flows into the Caspian Sea, dilutes its waters - 0.05% salt, but along the southeastern shores the salt content is 13%. The waters of the Caspian Sea wash the shores of five states at once: Russia, Azerbaijan, Kazakhstan, Turkmenistan, Iran. In the latter, these expanses of water are called differently - the Khazar or Mazandaran Sea. One of the mysteries of the Caspian Sea is the periodic fluctuation of water levels. Over the past three thousand years, the water level has changed by 15 meters, and these processes continue today. For example, from 1978 to 1995 the water level rose, from 1996 to 2001 it decreased, and then began to rise again. One of the reasons for the lake “disturbance” is possibly human activity. The Caspian Sea is known for its oil reserves, however, while gaining some wealth, we risk losing others. It is in these waters that most of the sturgeon stocks in the world are located. More than 90% of the sturgeon on the planet are caught in the Caspian Sea, and today the protection of the Caspian Lake is one of the main environmental tasks for Russia.

Ladoga lake

The largest freshwater body of water in Europe is Lake Ladoga, which is located in Karelia and the Leningrad region. 35 rivers flow into the lake, whose area is slightly more than 18,000 km2, and only the Neva, on which St. Petersburg stands, flows out. It was on Ladoga, thanks to the efforts of Peter I, that the Russian fleet was born. In addition, during the Second World War, ice Lake Ladoga"The Road of Life" took place. Thanks to it, food was supplied to besieged Leningrad, and about a million people were evacuated through it. In the northern part of the lake there are 500 of the 660 islands belonging to Ladoga. The Valaam archipelago, on which the ancient Spaso-Preobrazhensky Monastery is located, is especially famous. The harsh Lake Ladoga is often compared to the sea: winds often blow here, and if you swim to the middle of Ladoga, you will not be able to see the opposite shore.

Lake Ilmen is one of the symbols of Russian history, since the Slavs appeared in this region back in the 8th-9th centuries, at the time of the birth of the state of Rus'. Ilmen has been glorified in many tales, epics, poems and legends.

How Sadko went to Lake Ilmen,
Sat on a white-flammable stone
And he began to play spring goosebumps.

One of the largest lakes in the European part of Russia is located on the territory of Pskov, Tver and Novgorod regions. Lake Ilmen was recognized natural monument Russia. Unfortunately, the life cycle of the lake is ending, and Ilmen is classified as a “dying lake.” Its waters are gradually becoming swampy, the amount of silt is increasing, and the lake itself is slowly but still becoming shallow.

Pskovsko-Chudskoye Lake

“The Battle of the Ice took place on the ice of Lake Peipus in 1242” - we know about these events from the school curriculum, and it was thanks to them that Pskov-Peipus Lake, as it is called today, became famous. But not everyone knows that in fact the battle took place on the shore, and not on the ice, and Nevsky’s army was driving the retreating knights across the frozen lake. This fact was established in 1959 by an expedition of the USSR Academy of Sciences. The same group also determined the exact location of the events - Lake Teploe, which, like Pskov, as well as Lake Peipsi, is part of Lake Peipsi. About 30 rivers flow into this lake complex, and only the Narva River flows out. Best time for a trip to the lake - the first or second Sunday of April, when reenactors gather at Chudskoye to recreate the events of the Battle of the Ice.

Russia is a country with rich and unique natural resources, it has something to surprise and amaze: with forests, rivers, fields, and of course its lakes too, which are also called “ blue eyes our planet,” which is undoubtedly very beautiful and poetic. On its territory Russian Federation There are about two million lakes, their total area is 350 thousand km 2, the volume of water in all lakes is more than 26 thousand m 3. Most of the lakes are of glacial origin.

Large lakes of Russia

The largest lakes located in the European part of Russia are Onega, Ladoga, Chudsko-Pskov, Ilmen, and a huge number of lakes in the “lake region” of the Republic of Karelia.

The lakes of the Asian part of Russia are the Caspian Sea-lake, Lake Baikal, Russia's northernmost lake Taimyr, the Far Eastern Lake Khanka and the salt lake Chany in southwestern Siberia.

The Caspian Lake is the largest closed, closed reservoir on Earth, its area is 371 thousand km 2, and its level is 28 meters below sea level (in Russia this is the Baltic Sea). Due to the large size and specific structure of the bed (it contains the oceanic crust), it is also called the sea. The conventional border between Europe and Asia runs along its surface; it washes the shores of Russia, Azerbaijan, Kazakhstan, Turkmenistan and Iran. The Russian Caspian region is the territory of the Republic of Dagestan, Kalmykia, Astrakhan region(northern and northwestern part of the Caspian Sea)...

Lake Baikal is one of the most scenic spots our country, this is the deepest lake on the planet; huge reserves of fresh water are stored here - 85% of all Russian reserves and 22% of the world's.

Baikal - ancient lake, it is about 30 million years old, its basin is located in a rift basin, its water is particularly clean and transparent, the area around the lake (mountains, hills, dense deciduous forests) is uniquely picturesque...

The northern and eastern coasts of Lake Ladoga are located in the Republic of Karelia, the southern and western coasts are in the Leningrad region. Its area together with the islands is 18.3 thousand km 2, it is the largest freshwater lake in Europe. Has access to Atlantic Ocean, more than 40 rivers and lakes flow into it, the Neva River flows out (it flows into the Gulf of Finland Baltic Sea, which is part of the Atlantic). In the southern part there are three large bays, large cities on its coast - Priozersk, Shlisselburg, Novaya Ladoga ( Leningrad region), Sortavala, Lakhdenpokhya (Karelia)...

Located in the north-west of Russia Lake Onega, 80% of it is located on the territory of the Republic of Karelia, 20% - in the Leningrad and Vologda regions. Its area together with the islands is 9.7 thousand km 2, it is the second largest freshwater lake in Europe. The lake basin is located at the junction of the Baltic Shield and the Russian Platform. About 50 rivers carry their waters into the lake, only one flows out - the Svir. Kondopoga, Petrozavodsk, Medvezhyegorsk (Republic of Karelia) were built on its banks...

Lake Taimyr with an area of ​​4.5 thousand km2 is called the “northern brother” of Baikal, because it is the second largest in area fresh lake in the Asian part of Russia. It is located on the Taimyr Peninsula in the Krasnoyarsk Territory of the Russian Federation. The lake is located beyond the Arctic Circle, its surface is covered with ice from September to July. The Upper Taimyr flows into it, and the Lower Taimyr (Kara Sea basin) flows out...

There are about 5 million lakes in the world, but we have only heard about a few of the largest ones. Do you think that Baikal is the largest lake in the world? In fact, Baikal takes only 7th place in the ranking of the largest lakes!

The largest lake in the world- Caspian Sea.

The Caspian Sea tops the ranking - despite the fact that it is called a sea, in fact it is the largest endorheic lake on the planet. It is located at the junction of Europe and Asia, and is called a sea only because of its size. The Caspian Sea is an endorheic lake, and the water in it is salty, from 0.05 ‰ near the mouth of the Volga to 11-13 ‰ in the southeast.

The Caspian Sea is shaped like the Latin letter S, its length from north to south is approximately 1200 kilometers, from west to east - from 195 to 435 kilometers, on average 310-320 kilometers.

The Caspian Sea is conventionally divided according to physical and geographical conditions into 3 parts - the Northern Caspian, the Middle Caspian and the Southern Caspian. The conditional border between the Northern and Middle Caspian Seas runs along the line Chechen (island) - Tyub-Karagansky Cape, between the Middle and Southern Caspian Seas - along the line Zhilaya (island) - Gan-Gulu (cape). The area of ​​the Northern, Middle and Southern Caspian Sea is respectively 25, 36, 39 percent of the total area of ​​the Caspian Sea.

The length of the coastline of the Caspian Sea is estimated at approximately 6,500 - 6,700 kilometers, with islands - up to 7,000 kilometers. The shores of the Caspian Sea in most of its territory are low-lying and smooth. In the northern part, the coastline is indented by water channels and islands of the Volga and Ural deltas, the banks are low and swampy, and the water surface in many places is covered with thickets.

On east coast Limestone coasts predominate, adjacent to semi-deserts and deserts. The most winding shores are on the western coast in the area of ​​the Absheron Peninsula and on the eastern coast in the area of ​​the Kazakh Gulf and Kara-Bogaz-Gol.

The territory adjacent to the Caspian Sea is called the Caspian region.

Area and volume of water Caspian Sea varies significantly depending on fluctuations in water level. At a water level of 26.75 m, the area is approximately 371,000 km square kilometers, the volume of water is 78,648 cubic kilometers, which is approximately 44 percent of the world's lake water reserves. The maximum depth of the Caspian Sea is in the South Caspian depression, 1025 meters from its surface level. In terms of maximum depth, the Caspian Sea is second only to Baikal (1620 m) and Tanganyika (1435 m). The average depth of the Caspian Sea is 208 meters. In the same time Northern part The Caspian Sea is shallow, its maximum depth does not exceed 25 meters, and average depth- 4 meters.

Confidently secured second place among lake superior- the largest, deepest and coldest of the Great Lakes and, concurrently, the largest freshwater lake in the world.

In the north, Lake Superior is bounded by the Canadian province of Ontario, in the west by the American state of Minnesota, and in the south by the states of Wisconsin and Michigan.

The basins of Lake Superior and the northern part of Lake Huron were developed in the crystalline rocks of the southern part of the Canadian Shield, the basins of the remaining lakes were developed in the limestone, dolomite and sandstone of the Paleozoic North American Platform. The basin of Lake Superior was formed as a result of tectonic movements, pre-glacial river and glacial erosion.

The origin of the water mass of Lake Superior is associated with the melting of the ice sheet, during the retreat of which a number of large lakes were formed in this area, which repeatedly changed their outlines.

In the northern part of the Great Lakes, the coastline is dissected, the islands and shores (up to 400 m high) are rocky, steep, very picturesque, especially the shores of Lake Superior and the northern part of Lake Huron.

Fluctuations in the level of Lake Superior are artificially regulated for the purposes of navigation, energy, etc. The amplitude of seasonal fluctuations is 30-60 cm, the highest level is observed in summer, the lowest in winter. Short-term fluctuations in level caused by strong surge winds and seiches reach 3-4 m, tidal height is 3-4 cm

The third is Lake Victoria, a lake in East Africa, in Tanzania, Kenya and Uganda. Located in the tectonic trough of the East African Platform, at an altitude of 1134 m. It is the 2nd largest freshwater lake in the world after Lake Superior and the largest lake in Africa

The lake was discovered and named in honor of Queen Victoria by British traveler John Henning Speke in 1858.

Square Lake Victoria 68 thousand km. sq., length 320 km, greatest width 275 km. It is part of the Victoria Reservoir. Many islands. The high-water Kagera River flows in and the Victoria Nile River flows out. The lake is navigable, local residents They are engaged in fishing on it.

The northern coast of the lake crosses the equator. Lake at maximum depth 80 m refers to fairly deep lakes.

Unlike its deep-sea neighbors Tanganyika and Nyasa, which lie within the African gorge system, Lake Victoria fills the shallow depression between the eastern and western sides of the Great Gorge valley. The lake receives a huge amount of water from rain, more than from all its tributaries.

30 million people live in the vicinity of the lake. On the southern and western shores of the lake live the Haya people, who knew how to grow coffee long before the arrival of Europeans. Main ports: Entebbe (Uganda), Mwanza, Bukoba (Tanzania), Kisumu (Kenya), near the northern coast of Kampala, the capital of Uganda.

Lake Huron is the fourth largest among. This lake is in the USA and Canada, one of the North American Great Lakes. Located east of the lake Michigan, connected to it by the Straits of Mackinac. From a hydrographic point of view, Michigan and Huron form a single system (they are connected by the Strait of Mackinac), but geographically they are considered to be separate lakes.

The area of ​​Huron is about 59.6 thousand square kilometers (the second largest among the Great Lakes). The surface height above sea level is about 176 m (same as Michigan), the depth is up to 229 m.

The states of Michigan and the Canadian province of Ontario have access to the lake. The main ports on Huron are Saginaw, Bay City, Alpina (USA) and Sarnia (Canada).

The name of the lake, introduced by the French, comes from the name of the Huron Indian tribe. Manitoulin is located on Huron - the most big Island world, located in a fresh lake.

In the middle of the list, in 5th place among is lake michigan- one of the North American Great Lakes.

The only Great Lakes located entirely within the United States. Located south of the lake The upper one is connected to Lake Huron by the Strait of Mackinac, with the Mississippi River system - the Chicago - Lockport Canal.

From a hydrographic point of view, Michigan and Huron form a single system, but geographically they are considered to be separate lakes.

Square Michigan- about 57,750 km2 (the third largest among the Great Lakes), length about 500 km, width about 190 km. The surface height above sea level is 177 m (same as Huron), the depth is up to 281 m. It is covered with ice for about four months a year. Islands - Beaver, North Manitou, South Manitou.

The states of Michigan, Indiana, Illinois and Wisconsin have access to the lake. Big cities on Lake Michigan include Chicago, Evanston and Highland Park (IL), Milwaukee and Green Bay (WI), and Gary and Hammond (IN).

The name of the lake comes from the word mishigami, meaning “big water” in the Ojibwa Indian language. The first European to discover the lake was the Frenchman Jean Nicolet in 1634.

Sixth among is Aral Sea.

The Aral Sea is endorheic salt Lake V Central Asia, on the border of Kazakhstan and Uzbekistan. Since the 1960s of the 20th century, sea level (and the volume of water in it) has been rapidly declining due to the withdrawal of water from the main feeding rivers Amu Darya and Syr Darya for irrigation purposes. Before the start of shallowing, the Aral Sea was the fourth largest lake in the world.

Collector-drainage waters flowing from the fields into the bed of the Syr Darya and Amu Darya have caused deposits of pesticides and various other agricultural pesticides, appearing in places on 54 thousand square kilometers of the former seabed covered with salt. Dust storms carry salt, dust and toxic chemicals up to 500 km. Sodium bicarbonate, sodium chloride and sodium sulfate are airborne and kill or retard the development of natural vegetation and crops. Local population suffers from a high prevalence of respiratory diseases, anemia, cancer of the larynx and esophagus, and digestive disorders. Liver and kidney diseases and eye diseases have become more frequent.

In 2001, as a result of a drop in water level, Vozrozhdenie Island connected with the mainland. On this island, the Soviet Union tested bacteriological weapons: the causative agents of anthrax, tularemia, brucellosis, plague, typhoid, smallpox, as well as botulinum toxin were tested here on horses, monkeys, sheep, donkeys and other laboratory animals. This is the reason for fears that deadly microorganisms have remained viable, and infected rodents may spread them to other regions.

According to scientists' calculations, it is no longer possible to save the Aral Sea. Even if we completely abandon the intake of water from the Amu Darya and Syr Darya, the previous water level in it will be restored no earlier than in 200 years.

The Aral Sea once occupied 68 thousand square kilometers and was the fourth largest in area in the world. Now its area is about 10% of that recorded in the 60s of the last century. Photos from 1989 and 2003:

From the 1950s to the present, projects have been repeatedly proposed to build a canal to transfer water from the Ob basin to the Aral Sea basin, which would significantly develop the economy of the Aral region (in particular, agriculture) and partially revive the Aral Sea. Such construction will require very large material costs (on the part of several states - Russia, Kazakhstan, Uzbekistan), so there is no talk yet about the practical implementation of these projects.

Some scientists predict Aral Sea complete disappearance by 2020...

Lake Tanganyika- a large lake in Central Africa. This is one of and equally ancient in origin. In terms of volume and depth, Tanganyika ranks second after Lake Baikal. The shores of the lake belong to four countries - the Democratic Republic of the Congo, Tanzania, Zambia and Burundi.

The length of the lake is about 650 km, width is 40-80 km. Area 34 thousand sq. km. It lies at an altitude of 773 meters above sea level in the tectonic basin of the East African Rift Zone. Coastal landscapes, as a rule, are huge cliffs and only with east side the banks are flat. On the west coast, the steep sidewalls of the East African Rift Zone that form the coastline reach 2000 m in height. Coastline dotted with bays and bays. The largest of them is Burton Bay. The lake is fed by several tributaries. The only river that flows out is the Lukuga, which begins in the middle part west coast and flows west, connecting with the Zaire River, which flows into the Atlantic.

The lake is home to hippopotamuses, crocodiles, and many waterfowl. Fishing and shipping are well developed.

The antiquity of the lake and the long period of isolation resulted in the development of a large number of endemic organisms, including those from the family Cichlidae (cichlids). Of the more than 200 species of fish found in the lake, about 170 are endemic.

Tanganyika is inhabited to approximately a depth of 200 m; below this level there is a high concentration of hydrogen sulfide and there is no life until the very bottom. This layer of the lake is a huge “burial ground” consisting of organic silt and sedimentary mineral compounds.

The water temperature of Tanganyika varies strictly among layers. Thus, in the upper layer the temperature ranges from 24 to 30 degrees, with a decrease at greater depths. Due to different densities of water and the absence of bottom current, the layers do not mix, and the temperature on the lower horizons reaches only 6-8 degrees.

The depth of the temperature jump layer is about 100 m. The water of Tanganika is very transparent (up to 30 m). Many salts are dissolved in it in small concentrations, so its composition resembles highly diluted sea salt. Water hardness (mainly caused by magnesium salts) ranges from 8 to 15 degrees. Water has an alkaline reaction, pH 8.0 - 9.5.
